Abstract: PROBLEM TO BE SOLVED: To obtain a recording medium having ridge type protrusions plurally by performing a texture working by making an irradiation of a laser beam which has the beam shape of an elliptic shape or a rectangular shape having a projected curvature and moves relatively with a non-magnetic substrate on the medium from a light con verging mechanism by respectively inclining the major axis and the minor axis of a converged light spot of the laser beam by specific angles from the track width direction and the sector direction. SOLUTION: An incident laser beam on a light converging mechanism is irradiated by respectively inclining the major axis and the minor axis of the converged light spot of the lase beam by an angle of not larger than 45 degrees from the track width direction of the magnetic medium and by an angle within 45 degrees from the sector direction of the medium. The converged spot shape of the laser beam to be irradiated is an elliptic shape or a rectangular shape having the projected curvature and desirable length of the minor axis and the desirable length of the major axis of the converged spot diameter are respectively 1-3 μm, 2-20 μm.  The laser beam converged by the light converging mechanism is converged so as to become the smallest beam profile at a light-gathering point and the size is propertional to the wavelength to be used and is inversely proportional to the aperture of a lens to be used.

IPC: B01J47/02
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To effectively decrease sodium ion in colloidal silica used for the slurry for chemical mechanical grind by passing the colloidal silica through H<+> type ion exchange resin and successively passing through NH4 <+> type ion exchange resin. SOLUTION: The colloidal silica 3 is dropped from the upper part of a column 1, in which the H<+> type ion exchange resin 4 and NH4 <+> type ion exchange resin 5 form continuous two layers in one column 1 so that the H<+> type ion exchange resin is upside. The dropping rate of the colloidal silica 3 is usually SV of 5-70, preferably 15-40, wherein SV expresses the dropping quantity of the colloidal silica per 1 hr based on the resin capacity of the ion exchange resin. The min. required condition for obtaining the colloidal silica decreased in sodium ion is that the colloidal silica to be transferred to the NH4 <+> type ion exchange layer does not gel. The ratio (the H<+> type ion exchange resin) : (the NH4 <+> type ion exchange resin) is about 9:1 to (1:9).

Title: Eye open/close discriminating device
Inventor: USAMI SUKEYUKI
IPC: B60K28/06
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To surely discriminate whether eyes are opened or closed without being affected by any personal difference such as the direction of a face or the length of eyelashes by acquiring a face image, detecting the part of the upper eyelids from the face image and discriminating whether the eyes are opened or closed based on the shape of the upper eyelids. SOLUTION: A CPU finds the eyes out of the inputted face image. This processing is executed in the state of traveling while a car speed is higher than a prescribed value and a driver gazes at the front. Next, it is discriminated whether the eyes can be found out or not, and when the eyes are found out, the positions of these eyes are tracked in successively inputted face images. By labeling edge images, a part 100a (eye opening state) of the upper eyelids is extracted. Next, a part lower than the part 100a of the upper eyelids is binarized, and terminal points A and B on the left and right sides of the binarized part are extracted. Next, the binarized part is vertically bisected by a line connecting the terminal points A and B and the area ratio of upper and lower parts is calculated and stored. This area ratio becomes the opening degree of the eyes.
